Restrict areas to drop elements

Jun 26, 2012 at 9:25 PM

Again, fantastic program. I was wondering if anyone has figured out a way to restrict dropping an item in an area. I've implemented the ability to have some items stationary, but I need to figure out how to prevent some items being dropped between specific items. Whereas I've grouped some elements together, I dont want the user to be able to insert elements inside of this subgroup.

 

List is 1,2,3,4,5,6,7,8

4,5,6 are connected and move as a group

I dont want to a user to be able to place 8 in between 4 & 5 or 5&6.

Thanks
